1 I The main objects ofthelinvention are;

First, toprovide an improved treadmill exercising device which islvery efiicient and efiectual'and noiseless n operation.

5 Second, --to provide -an effective. control means for such a treadmill;

' Third, to provide a means whereby the user of a treadmill exerciser, is s'upported' in such manner as to allow the "free movement of the ning.

V *of construction and operation will definitely appear fr'om'the description to follow; The

15' invention is clearly-definedinthe claims.
